UncleMeat 1,174 Posted June 5, 2015 Posted June 5, 2015 I've always wondered if Left refers to the speaker to my left as I'm facing the speakers or if it's the speaker on the left side as the speaker faces the room (which would be the speaker to my right if I'm sitting facing them and listening). I've heard that many recordings are reverse channel so that would destroy the image that SH is trying to re-create. Can someone point out a recording that is reverse to what is supposed to be correct? Also; what channel is the outer groove on a record? Is it the Left channel? Does a stylus wear the side that faces the outer groove first, and is that the left channel (coming from the TT output) or the right?
RichP714 3,169 Posted June 5, 2015 Posted June 5, 2015 Since the conventions of disc recording dictate that the right stereo channel is recorded in the wall of the groove closest to the edge of the record' date=' and the left channel in the wall closest to the centre, it is clear from the micrographs that it is the right audio channel which is being subjected to excess force. Whether the differential wear pattern seen is due to stylus misalignment or to excess bias will determine which of the two channels will provide the first audible evidence of mistracking.[/quote']
mas52indy 82 Posted June 5, 2015 Posted June 5, 2015 When I was an undergraduate majoring in physics, I calculated the instantaneous force exerted by the stylus on the walls of the groove to be in excess of 1000 psi. After that, I was very careful about cleaning my vinyl so that microparticles would not become a permanent part of the disc.
dr_gallup 42 Posted June 5, 2015 Posted June 5, 2015 If I recall correctly, the left speaker is the speaker to your left when sitting in the listening position. Now I'm going to have to go home and verify that. My home theater system has an on screen display where you can adjust the level of every speaker one at a time so you can get them matched. A properly designed anti-skate mechanism should pretty well balance the wear on both sides of the grooves.
Balok 1,747 Posted June 5, 2015 Posted June 5, 2015 The back of yer amplifier will be labelled right and left at the binding posts. Go by that designation, methinks.
sKiZo 186 Posted June 5, 2015 Posted June 5, 2015 Get three speakers, put them all on the left side ... After all ... (wait for it) . . . Three lefts DO make a right ... (ba dump dump) I've always gone with how they orient towards the primary listening position.
